I&#39;...Excellent information, Jacques; thank you!<br /><br />I&#39;m aware this sort of math was known to theoreticians such as Ptolemy, Farabi, Avicenna, etc., but especially with regard to the Middle Eastern traditions, I&#39;m under the impression that such theory was rarely put into practice (see my previous post on Persian dastgah). I&#39;m less familiar with Hindustani/Carnatic traditions beyond a basic concept of srutis, but what I do know is there has been much contention on the actual nature of their tuning, and there is not likely to be a consensus any time soon. I likewise have only a basic knowledge of slendro and pelog, though I would dispute that they are known with certainty as being the oldest on the planet; from what I have read on the Internet (so it must be true!), a set of ancient Chinese flutes are the oldest confirmed musical artifact, and their scales are straight diatonic, and likewise a possible but unconfirmed section of a prehistoric bone flute has holes that strongly suggest a diatonic scale.<br /><br />While of course I don&#39;t consider any one source definitive, I have found David B. Doty&#39;s book &quot;The Just Intonation Primer&quot; exceedingly helpful. Doty details usages of primes through and beyond 19, though from 19 onward he questions their usefulness. I would not be surprised that primes through 13 are pretty standard within the JI world, but 5-limit seems like the most common (and ideal) introduction to these concepts for a musician born and raised in 12-TET.Jay Randomhttps://www.blogger.com/profile/13175160982263070325noreply@blogger.comtag:blogger.com,1999:blog-3973458659349895498.post-11695954494841201932011-06-28T04:53:49.378-05:002011-06-28T04:53:49.378-05:00Just intonation is old as the world and 13-limit s...Just intonation is old as the world and 13-limit scales models were known by the persians, greeks, and others for thousands of years. There is no way to escape the 13/8, 13/12, 16/13 ratios, etc. in arabian, turkish or persian music.<br />7th harmonic in combination with 3th harmonic proposes the most basic models for Slendro tunings, known as the oldest scales we know on Earth, as well as many Aka/Baka tunings.<br />17th and 19th harmonics ratios are completely pertinent in many european music cultures, indian and gypsy music.<br />Extended JI &quot;as passed 5-limit&quot; is less and less recognized as a standard in the JI world today. For many extended JI starts passed 13-limit and for more and more it starts passed 19-limit, at least.Jacques Dudonhttp://aeh.free.frnoreply@blogger.comtag:blogger.com,1999:blog-3973458659349895498.post-50037817260428800482011-06-27T16:35:50.462-05:002011-06-27T16:35:50.462-05:00Madness! ;-)Madness! ;-)Jay Randomhttps://www.blogger.com/profile/13175160982263070325noreply@blogger.comtag:blogger.com,1999:blog-3973458659349895498.post-88343413933851647972011-06-27T16:33:19.006-05:002011-06-27T16:33:19.006-05:00Not only are 3 and 5 sometimes excluded, some peop...Not only are 3 and 5 sometimes excluded, some people love to exclude 2.Gene Ward Smithhttps://www.blogger.com/profile/10283709324380558714noreply@blogger.com
